"System Administrators (SAs) have a tough job: Dealing with users and user accounts, security, patching, updates, upgrades, disk space, performance and other miscellaneous tasks often known as "other duties as assigned." For some SAs, the day never ends. Despite the challenges, pitfalls and occasional irate user; system administration is a fulfilling job with intangible rewards like no other position in IT. To assist those weary SAs in their quest to conquer their Linux systems, I've devised this list of 12 native Linux system monitoring tools that are always at my fingertips.

"Any user may issue these commands, if they exist and haven't been protected by the SA. They are harmless and are read-only commands. The only problem with them is that ordinary users might inform the SA of a performance problem before the SA knows about it and that can irritate an overworked SAs nervous system.

"1. top - It's only fitting that at the top of this list, that you'd see 'top.' Top is a diagnostic tool and a real time monitoring tool. Execute this command to see a running list of the top system resource consuming processes on a system. Try it for yourself by typing top at the command prompt. To quit top, press the 'q' key."
